GUIDING AND MARKING DEVICE FOR SEWING-MACHINES.

Specification of Letters Patent.

Patented Dec. 24, 1907;

Application filedAugus-tiB. 1907- Serial No. 387.672.

To all whom it may concern: Be it known that 1, CHRISTINA Lmnoue, a citizen of the United States, residing at Galeton, in the county of Potter and State 5-of1 ennsylvania,,have invented certain new and useful Improvements in Guiding and Marking Devices for SeWing-Mabhines, and

do declare the followingto be a full, clear, g

and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same.

Thisinvention relates to improvements in adjustable guiding and marking attachments for swing machines. The ob ect of the invention is to provide a guiding and marking attachment of this rcharacter which may be quickly and easily attached to a sewing machine to guide the rows of stitches and to mark a parallel line for the next row of stitching, whereby the hems, seams, tucks, 'or plaits, may be conveniently formed, or braid or trimming sewed on in even, parallel rows, means being provided whereby the guide may be adjusted to mark guide lines at various distances apart.

-W1th this object in view, the invention consists of certain novel features of construction, combination and arrangements of parts as willbe more fully described and particu- 80 'larly pointed out in the appended claims.

In the accompanyin drawing, Figure 1 is a perspective view of the device showing the same attached to the presser foot bar of a sewing machine; Fig. 2 is an enlarged front 36 view of the attachment partly in section; and 3 isan end elevation. of one end of the same. Referring more particularly to the drawings, 1 denotes the attachment, which comi i0] prises a pair of adjustably connected suppbrting bars, 2, which are adjustabl heldtogether by means of an aperturcr bolt, 3, jthrou h the a erture in which said rods are On t e bolt, 3, is arranged an at- I of whicharefolmed alined apertures 5, which "coincide with the aperture in the bolt and through which the bars or rods, 2, also project. aThe bolt, 3, is provided with a reduced threaded extension on which is adapted to be screwed a clampi: nut, 6, which, when screwed up on the tlircaded end of'thc bolt, will draw the'rods or bars 2 into tight en; gagement with the walls of the apertures, 5, clamping or holding the usted positions. The clip,

. same in their a 4, is provided with curved plates, .7, which are adapted to embrace the presser foot bar I of the machine, and in one of the plates 7 is formed a threaded aperture in which is arranged a clamping screw, 8, on the inner end of which is swiveled a curved clamping plate, 9, which, when the screw 8 is screwed inwardly, is adapted to clamp against the side of the presser foot bar and thus securely hold the attachment in place thereon.

"One end of each of the bars is reduced to form a shoulder, 10, and on said reduced ends of the bars are arranged standards, 12, of parallel guide feet, 13. The standards 1.2 are 70' clamped in position against the shoulders 10 of the bars, 2, by means of thumb nuts, 14, which are adapted to be screwed onto the redu'ced threaded ends of the bars,-as shown.

Adapted to be detachably engaged with the standards 12 of the guide -feet is a chalk holder 15, in the outer end of which is formed a tapered chalk receivi socket, 16. On the outegend of the hol er' 15 is formed a spring clamping plate .17, by means of which the holder is secured to either of the sup-' ports, 12. The rods of bars 2, are provided with a scale of measurements, whereby accu rate adjustments of the same may be made.

In the operation of the device, the clip, 4, is secured to the prcsser foot bar of the machine, as hereinbcfore described, and after which the bars, 2, are adjusted to bring the marking feet 13 to the desired position with res cct to the scam or row of stitching which is eing made by the machine, after which the clamping nut, 63, is tightened up to hold the bars in their adjusted position. The chalk holder is now applied to the proper guide foot standard so that as the row of 96 stitching is made by the machine, a chalk line will be drawn parallel therewith, and at the desired distance therefrom thus marking the place for the next row of stitching, as will be readily understood.

Having thus fully described my invention, what I claim as new and desire to'secure by Letters-Patent, is:

1. A guiding and marking attachment for sewing machines comprising a pair of adjustably'connected supporting bars, having arranged thereon a scale of measurements, means to securesaid bars to the presser foot bar of the machine, guide feet removably sesaid holder whereby the same is detachably secured to either of said guide feet, substantially as described. p

2. A guiding and marking attachment for sewing machines comprising a pair of adjustably connected supporting barshaving arranged thereon a scale of measurements, a fastening bolt having formed therein a transversely disposed passage to receive said bars, a fastening'clip having an aper'tured bolt engaginggiortion through which said bars are adapts to project, a clamping nut adapted to be screwed onto the threaded end of said bolt, whereby the supporting bars are rigidly held together in their adjusted positions guide feet standards'adapted to be secure upon the outer end of said supporting bars;

'to be engaged with said re ends, clamping nuts ada ted to be screwed onto said ends to hold said standards in engagement with said shoulderg'iand guide feet to be lengthened or shortened to adjust the device, a fastening clip adapted to be eng'aged with the presser oot bar of a machine, a clarnping screw arranged in said clip, a

clamping plate swiveled on the inner end of said screw and adapted to be engaged] there by with the resser foot bar, reduced threaded ends f drmed on said bars to provide shoulders, guide feet supports. adapted formed on the lower end of said standards, substantially as described.

In testimony whereof I have hereunto set my .handin presence of two subscribing wit- '40 nesses. j
